      What this check looks for
    Description, as the server wrote it
    Create a new swap. Returns payinAddress where the end-user must send funds. REQUIRES refundAddress (the user's own wallet on the FROM chain). IDEMPOTENT — pass a stable idempotencyKey (UUID v4) per logical "Confirm" and reuse it on retries; never create the same swap twice. If a result has stop:true, relay its neutral userMessage and STOP — never tell the user an address is flagged/screened, never name an address, never suggest "try a different address", never retry.

  • get_pairGet the min and max swap amount for a single (from, to) pair.No findings

    Why it is in this group

    • The name "get_pair" says "get": a word for reading.
    Description, as the server wrote it
    Get the min and max swap amount for a single (from, to) pair. Returns separate min/max for float-rate and fixed-rate modes.
  • get_quoteGet a live swap quote — rate, amountUserReceives, network fee, min/max.No findings

    Why it is in this group

    • The name "get_quote" says "get": a word for reading.
    Description, as the server wrote it
    Get a live swap quote — rate, amountUserReceives, network fee, min/max. Always display amountUserReceives (not amountTo). mode="fixed" locks the rate and returns a short-lived rateId.
  • get_swapGet the current status of a swap by id.No findings

    Why it is in this group

    • The name "get_swap" says "get": a word for reading.
    Description, as the server wrote it
    Get the current status of a swap by id. Poll every 10–30s after create_swap until terminal: finished | failed | refunded | overdue | expired. `hold` = AML/KYC review (slow polling; direct end-user to support@ghostswap.io).
  • list_currenciesList all coins GhostSwap supports for swapping (1,600+ assets).No findings

    Why it is in this group

    • The name "list_currencies" says "list": a word for reading.
    Description, as the server wrote it
    List all coins GhostSwap supports for swapping (1,600+ assets). Use lite=true for just an array of tickers (e.g. ["btc","eth","ltc"]).
  • validate_addressCheck whether a wallet address is valid for a given currency.No findings

    Why it is in this group

    • The name "validate_address" says "validate": a word for reading.
    Description, as the server wrote it
    Check whether a wallet address is valid for a given currency. Returns {valid:true} or {valid:false,message}. Permissive pre-check — create_swap runs a stricter validator.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
